Synthesis of N-(2-carboxy-thieno[2,3-b]pyridine-3-yl) amidines by the reaction of 4-oxo-4H-pyrido[3',2': 4,5]-thieno[3,2-d]1,3-oxazines with primary amines

The title compounds were synthesized by the reaction of tricyclic compounds of structure B with primary aliphatic amines under different conditions and useful isolation methods in good yields. These compounds showed an acceptable antianaphylactic activity.
